Description	The Red crystals of [PPh4]2[Se2Br6(Se2Br2)2] (1) were obtained when selenium and bromine reacted in the solution of acetonitrile in the presence of tetraphenylphosphonium bromide. The crystal structure of 1 has been determined by X-ray diffraction and refined to R = 0.0201 for 4024 reflections. The crystals are triclinic, space group P-1 with Z = 2 and a = 11.2757(4) A, b = 12.3347(5) A, c = 12.4948(5) A, = 113.152(4)deg, = 114.745(4)deg, = 91.208(3)deg (120(2) K). In the solid state the anion of 1 is built up of the Se2Br6 core and two Se2Br2 molecules each of which is linked to one of the trans-positioned terminal Brt atoms of the Se2Br6 core. The central Se2Br6 part consists of a nearly planar arrangement of two planar SeBr4 units sharing a common edge through two 2-bridging Br atoms. The contact between the Brt and the SeI atom of the Se2Br2 molecule is 3.0872(5) A and can be interpreted as a bond of the donor-acceptor type with the Brt as donor and the Se2Br2 molecule as acceptor.
